Definitions

  • the invention relates to a closure of the type mentioned in the preamble of claim 1 for a bottle or the like.
  • a closure in which, in addition to the radial sealing face on the end face, axial sealing faces are provided in the region of the mouth edge of a bottle, into which the sealing compound of the seal extends.
  • the sealing part is deep-drawn and extends around the mouth of the bottle so as to form the outer, axial sealing surface.
  • the essence of this known closure should consist in the fact that the sealing part, at least in a partial area at the transition from the sealing part to the holding part, is not deep-drawn down to the lateral mouth edge of the neck of the bottle, but is rather excluded from such a deformation. In this way, a reduced sealing distance is to be created in the undeformed partial area, which, due to its brevity, should result in less tightness.
  • a closure for a bottle or the like which has a cap-shaped holding part on which there is an inwardly directed projection or collar for engaging behind an outer bead of a bottle neck.
  • This holding part is connected via an elastic element to a sealing part with an annular sealing surface for contact with an end face of the bottle neck.
  • the holding part has a stop for the defined contact of the holding part on the edge of the bottle neck. Since the sealing part also abuts the edge of the bottle neck, the mutual position of the holding part and the sealing part is precisely defined. Since the elastic element for prestressing the sealing part is located between the two, the size of the prestressing of the elastic element is also precisely defined and thus the pressure at which the sealing part lifts off, that is to say opens the pressure relief valve.
  • the inside of the bottle for example a beverage liquid
  • a screw cap for a bottle or the like in the bottom of which a seal is arranged which consists of three layers, namely a back layer and a front layer running parallel to it and spaced parallel to it, which via a flexible intermediate layer in Shape of wavy and sloping supports are kept at a distance from each other. Due to their shape, these supports give the overall seal compressibility. Due to this compressibility, excess pressure can escape from the bottle if it is large enough to compress the seal and thus lift it off the front edge of the bottle neck. The opening pressure therefore depends on the compression of the resilient seal, which in turn depends on the screwing torque. There is thus no independence of the opening pressure from the screwing torque, which can be very different, especially when screwing on by hand. This means that the risk of bottles bursting and thus the risk of injury is not avoided.
  • the invention has for its object to provide a closure of the type in question, which is simple in construction and largely reliably independent of the screwing torque opens at a predetermined pressure.
  • the invention frees itself from the known idea of pressing the sealing part as a whole against the mouth of the bottle neck via an elastic element. Rather, the basic idea of the invention is to create a seal, stop and elastic element only by the design of the seal.
  • the seal has a constant thickness and consists of material of different compressibility over the circumference.
  • the locations of low compressibility form stops, while the locations of greater compressibility can stand out at a predetermined overpressure, so that an overpressure is formed.
  • the material of the seal can have cavities, in particular bubbles, at some points, as a result of which foam is practically formed at these points.
  • the material of the holding and sealing part can be any, for. B. plastic or metal. It can be a screw or crown closure or any other closure.
  • a holding part 1 and a sealing part 2 together form a screw cap, for which purpose threads 3 are provided in the holding part 1, with which the holding part 1 can be screwed onto bead-shaped threads 4 of a bottle neck 5 of a bottle 6, which is only partially shown.
  • Holding part 1 and sealing part 2 are deep-drawn and / or pressed from aluminum, as is generally the case with screw closures of this type.
  • the sealing part 2 In its edge area, the sealing part 2 has a flat, annular sealing surface 7, between which and one End face of the bottle neck 5 there is a seal 8, which has the same cross-section, that is to say the same thickness over the circumference.
  • this seal 8 has three areas 9, 10 and 11, which have a lower, preferably substantially less compressibility than a central area 12. These areas 9, 10 and 11 thus act as stops and determine the compression of the central region 12 of the seal 8 in the region of the sealing surface. At these points, the material of the seal can therefore lift off the sealing support at a certain excess pressure and thus allow excess pressure to escape.

Obturateur pour une bouteille ou similaire, avec une partie d'arrêt qui présente une saillie dirigée vers l'intérieur ou collerette pour venir en prise derrière un bourrelet extérieur d'un col de bouteille, avec une partie d'étanchéité reliée à la partie d'arrêt qui présente une surface d'étanchéité essentiellement annulaire et avec une garniture d'étanchéité en matériau compressible et d'épaisseur constante, disposée entre la surface frontale annulaire du col de bouteille et, à l'état fermé, en appui sous pression variable en direction périphérique aussi bien sur la surface d'étanchéité de la partie d'étanchéité qu'également sur la surface frontale du col de bouteille, caractérisé en ce que la garniture d'étanchéité présente sur la périphérie, à au moins un emplacement, un matériau de compressibilité plus faible.
  2. Obturateur selon la revendication 1,
    caractérisé en ce que la compressibilité plus faible est créée par des volumes creux ou des évidements sur la face de la garniture d'étanchéité écartée de la surface d'étanchéité.
